Toggle/Loadable Flip-Flop with Toggle and Clock Enable and Synchronous Reset and Set
The synchronous reset input (R), when High, overrides all other inputs and resets the data output (Q) Low. (Reset has precedence over Set.) When R is Low and synchronous set input (S) is High, the clock enable input (CE) is overridden and output Q is set High. When R and S are Low and load enable input (L) is High, CE is overridden and data on data input (D) is loaded into the flip-flop during the Low-to-High clock transition. When R, S, and L are Low and CE is High, output Q toggles, or changes state, during the Low-to-High clock transition. When CE is Low, clock transitions are ignored.
